Overload Relay, 50-200A, for Motor Protection, S6, CLASS 5-30, Manual-Automatic-RESET – 3RB21534FW2

Overload relay 50...200 A for motor protection size S6, CLASS 5...30E Contactor mounting/stand-alone installation Main circuit: Busbar. Auxiliary circuit: screw terminal. Manual-automatic RESET internal ground fault detection Electronic overload relay SIRIUS 3RB2 for current-dependent protection of loads with normal and heavy starting against impermissibly high heating due to overload, phase unbalance or phase failure. Thanks to wide current setting ranges and different trip characteristics, entire series of motors are covered with just a few types. With their low power loss, they are particularly energy-efficient and contribute to less heat in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous areas (ATEX) are a matter of course. The 3RB21 version offers extended functionalities such as integrated electrical remote reset, ground fault detection and much more. Available with different setting ranges for the overload release and with different trip classes. They are available with screw or spring-loaded terminals for a fast, maintenance-free and vibration-proof connection, as well as for stand-alone installation. The accessories fit consistently for all sizes S6 to S12. Simple, efficient, always up-to-date - the SIRIUS modular system.
